##### Reference no: EM13271956

an airplane with a wingspan of 100m flies parallel to the earth's surface at a point where the downward component of the earth's magnetic field is 0.500 x 10^-4 T. This airplane is equipped with a voltmeter that can measure the electric potential difference between one edge of the wing and the other edge. If the airplane is flying with speed of 200 m/s, what is the reading of the voltmeter?
